OpenTsdb: Is Space character allowed in Metric and tag information

I was working with openTsdb and came across with the issue that space character is not allowed in metric, tag(tagk) and even the values(tagv). Is there any way we can add space atleast in the value of tag?

I also referred: http://opentsdb.net/docs/build/html/user_guide/writing/index.html#metrics-and-tags

Solution

  • Spaces are not allowed.

    As per the documentation you referred:

    Only the following characters are allowed: a to z, A to Z, 0 to 9, -, _, ., / or Unicode letters (as per the specification)

    I suggest you should use '_' in stead of spaces.
